Patent GB-624415-A (GB)
Title: Improvements in or relating to process of separating fatty acids
IPC: C11C1/00
Filed: 1945-09-05
Abstract: A mixture of C12-C24 fatty acids obtained by splitting fats is blown with air under pressure for a time sufficient to effect an increase in the neutral fat content thereof and then the airblown fatty acids are dissolved in a solvent and the solution cooled.  Easily filterable crystals of the solid fatty acids present separate.  By crystallizing the solid acids and separating them from the liquid acids in two or more steps at progressively lower temperatures, solid fatty acid fractions richer in stearic acid than palmitic acid and other fatty acid fractions richer in palmitic acid than stearic acid may be obtained.  Oleic acid of substantially zero titre may be recovered from the mother liquor after removal of the solids. Fats which may be split to provide the starting materials are tallow, brown grease, garbage grease and like animal fats, while solvents which may be used are water-miscible polar liquids such as methyl alcohol, ethyl alcohol, isopropyl alcohol and acetone. In the examples, fatty acids from mixtures of tallow and garbage grease are blown with air, dissolved in aqueous methanol, the solution cooled and the crystals separated.  Specification 643,851 is referred to.
